Jesus rebuked two of his disciples who sought for His permission to call down fire from heaven upon a Samaritan village that did not receive him. He told James and John that they did not know the kind of spirit they had and reminded them that he did not come to destroy men's lives but to save them. Although his disciples, they were quite unlike Christ, looking unto Elijah instead of the author and finisher of their faith.

The heart of the believer is tender and needs to be constantly watched over to avoid corruption and defilement. When God justifies a man, and makes him righteous at salvation, He also gives him the charge to keep himself pure. Failing in the responsibility to take away the things that have the capacity to defile a man will eventually result in eternal damnation. The believer is therefore expected to eschew evil and to abstain from all appearance of it.

The faith that really works is the faith that does work. It is living, active and productive faith. Dormant or idle faith on the other hand is dead and produces no result. That is the faith that says "I believe in God" or "I know God" but continues in disobedience to the word of God. Therefore to him that knoweth to do good, and doeth it not, to him it is sin - James 4:17. 

Faith makes the believer bigger than their actual appearance. All that you need to do exploits in the kingdom of God is faith as small as a mustard seed. Every believer has this size of faith but unfortunately many are not aware of this fact. When his disciples asked the Lord to increase their faith, he told them all they needed was faith as small as a mustard seed - Luke 17:6.

A baby that is born complete with all the members of the body does not immediately know how to use those members to their full potential. For instance, he may hear the sound of spoken words but is unable to make sense out of what is being said. Also, though the baby may make sounds with his mouth, he'll not be understood by grown-ups. The newborn baby needs food for physical growth and development.
